Micromem Technologies Launches Ultra-Sensitive Liquid-Phase Sensor Targeting Disease Biomarkers with Breakthrough Picomolar Detection

Toronto, Ontario and New York, New York, August 11, 2025 - Micromem Technologies Inc. ("Micromem" or the "Company") (CSE: MRM, OTCQB: MMTIF) is pleased to announce the successful development of its liquid-phase nanowire bio-chemical sensor, engineered to detect disease-associated biomarkers at ultra-low concentrations. This innovation marks a critical milestone in the pursuit of more accurate, earlier medical diagnostics.

The sensor has demonstrated limit-of-detection performance down to 1 picomolar (pM) and 20mV/decade sensitivity, enabling the identification of inflammatory and pathological biomarkers previously undetectable by conventional methods. The sensor platform is fabricated using standard photolithography processes, making it both cost-effective and scalable for high-volume industrial applications.

The initial target analyte is TREM-1 (Triggering Receptor Expressed on Myeloid Cells 1), a key marker known to amplify inflammatory responses and closely associated with a range of diseases including atherosclerosis, cancer, colitis, and fibrosis.

Platform Highlights:

Ultra-Low Detection Thresholds: Achieves pM-level detection, suitable for early-stage disease monitoring.
Broad Diagnostic Utility: Customizable for other critical biomarkers involved in cancer, autoimmune disease, and systemic inflammation.
High Signal Clarity: Nanowire-based response delivers real-time, low-noise output with a strong correlation to analyte concentration.
Compact and Integratable: Ready for deployment in next-generation lab-on-a-chip, point-of-care, or remote diagnostic devices.
Manufactured via conventional photolithography techniques, the platform supports efficient, low-cost production-critical for widespread adoption in clinical and point-of-care diagnostics.

Market Relevance

With global demand for biomarker diagnostics expected to exceed $100 billion USD by 2030¹, Micromem's platform presents a compelling opportunity for partnerships with biotech, pharmaceutical, and diagnostics companies seeking next-generation sensor technologies.

This liquid-phase sensor platform originated from work developed on behalf of the Department of National Defence and is evolving into a commercial diagnostic tool.
